suberization

Increased rates of suberization and lignification in the exodermis may lead to a greater resistance to the entry of materials into the root apoplast.

The roles in defence include oxidation of hydroxy-cinnamyl alcohols into free radical intermediates, phenol oxidation, cross-linking of polysaccharides and of extensin monomers, lignification and suberization.

These changes have been mostly investigated over a long-term period and are clearly associated with profound anatomical adaptations including the suberization and lignification of cell walls.
